To all whom it may concer/n:

Y Be it known that I, .EDwrN F. BEUGLER, a citizen of the United States,residing in Buffalo, in the county of Erie and State of New York, haveinvented newv and useful Improvements in Machines for MakingBarrels, ofwhich the following is a specifica- This invention relates rgenerally toma-v chines for making barrels, but more particularly, to a machine,vfor compressing the staves about the head to permitfthe hoops tobefitted thereon.

OneV ofthe objects of the invention is to provide an improved poweractuated ma chine of this` character which is simple and compact inconstruction, and which is ecient in operation and easily controlled.

A further object is to improve the stavecompressing mechanism with aview of contracting the staves uniformly. and with equal pressureAthroughout the 'circumference of the barrel.r` i

l1 arranged near its vrear end for supporting the compressor arms andthe actuating mechanism.

12, 12 indicate the compressor arms, which, as shown in Fig. 2, are ofsubstan? tia'lly semi-cir`cular form so that they together partiallyencircle the vbarrel when compressed. These 'compressor arms overhang`the platform portion of the kbase 10 i andere adapted to swinghorizontally to? ward and from one another for compressing p the stavesof a barrel at a point below its upper end. The opposing rear ends ofthe arms are pivoted or hinged to an upright post 13 suitably journaledin the upper front portion of the base extension 11. One of these armsisprovided with a collar-,14 fastened by a set screw 15 to the post whilethe other arm is provided witha fork 1G loosely' {ittingthe postandembracing said collar. Y r f 17 indicates an upright shaft arrangedparallel with the post 13 and journaledin suitable bearings formedr inthe baser exten# v sion 11 and provided at itsupper-end with abell-crank lever 18 having a comparatively long arm 19 and a short army20. This bell-crank 'lever is operatively connected to the compressorarmsv by toggle 'links 21 22 sothatlwhen said lever is turned in one direction or theV othery the arms are caused to swing in a correspondingdirection. For this purpose, the 'links are preferably aper tured attheir ends and the compressorarms are provided with rearwardly extendinglugs orA brackets 23 to which the outer ends of the links` are pivotedby pins 241 while their inner ends arel pivoted by pins 25k to thecorresponding arms of a bell crank-lever. vAny, suitable-means may beemployed for transmitting motion tol the shaft 1 7, for the purpose ofcontracting the compressor arms 12, 12' about the barrel, but as showninthe drawings, this is preferably effected by providing saidy shaft atits lower end with a wormk wheel V26 which is loosely mounted thereonand constantly'in mesh with a worm 27- fxed on a horizontal drivingshaft 2 8.

The latter is journaled "at its ends in bearing brackets 29 mounted pnthe rear portion of thebase 10 of the machine, shown in Figs. lIl and 2.This driving Shaft is p170 Yidedvith tightens laos@ Pulleys- Oi- 31,which may be Connected by a belt (not shown) 'to any ,suitahe 5911?@ ofYmwen The driven shaft 17 is controlled by a friction clutch consistingof a female member 32 formed integrally with the worm wheel 2G and amalemember splined on said shaft and movable vertically thereon into and outof engagement with its companion female member. The shifting of the maleclutch member into and out of engagement with its female member iseffected by a verticallyswinging clutch lever 34 fulcrumed at to theupright extension 11 and provided at its rear end with a fork B6engaging a grooved collar 87 formed on said male clutch member. rIhisrock lever is actuated by a foot lever 38 piveted at 239 to the lefthand side of the base 10 and connected by a link 40 with the front armof said clutch lever. A coil spring 41 applied to the rear arm of saidclutch lever normally tends to hold the clutch in its released orinoperative position. By depressing the foot lever the clutch is movedto its engaged or operative position. 1n the fully contracted positionof the compressor arms about the barrel, as shown in Fig. 2, the sameare selflocking inasmuch as the pivotal of the toggle links 21, 22 areon a dead center line with the axis of the driven shaft 17.

In order to unlock the compressor arms and permit them to be moved totheir open or expanded position, shown by dotted lines in Fig. 2, amanually operated device is employed which preferably consists of areleasing member 42 in the form of a bell crank lever turning in avertical plane and fulcrumed at 48 to the upper rear portion of the baseextension 11. This releasing member is adapted to engage its uprightrear arm with a rearwardly facing shoulder 44 formed on the short arm 20of the bell crank lever 18 so asto turn the same in the proper directionto break the dead center position of the toggle links. For the purposeof conveniently actuating the releasing member, a foot lever 45fulcrumed at 46 is provided, a link 47 serving to operatively connectsaid foot lever with the horizontal front arm of the releasing member,as shown in Fig. l.

After the breaking of the toggle connection between the compressor armsand the bell crank lever 18, through the medium of the releasing device42, a coiled spring 48 is employed for automatically returning saidcompressor arms to their open or normal position. The ends of thisspring are attached to vperforated lugs 49 formed on the opposing` innerends of the compressor arms, as shown in Fig. 6.

Means are provided for cushioning the compressor arms at the end oftheir return movement so as to prevent any undue shock and strain on thesame and associated parts. To this end the opposing inner ends of thecompressor arms are provided with sockets 50 and suitably guided in eachof them is a horizontal bolt 51 havinea coiled spring 52 encircling thesame, said spring bearing at one end against the bottom of the respee*tive socket and at its other end against the bolt head. The heads of thebolts project beyond the opposing open ends of the sockets 50 and areadapted to contact with `ach other when the compressor arms areautomatically opened to the position shown in Fig. 8.

rlhe compressor arms 12 do not themselves touch the barrel, but each armis provided with a series of curved segmental jaws or plates 53yieldingly mounted thereon so as to come into contact with the barrelstaves when the compressor arms are closed or contracted. Any suitablemeans may be employed for yieldingrly mounting those jaws or plates sothat they are permitted a certain range of movement to adapt them to theirregularities in the shape of the barrels. As shown in Figs. 1, 2 and7, each of the segmental plates is adjustably mounted on a radiallymovable slide 54 guided in a dovetail way 55 formed in the upper side ofthe respertive compressor arm. An upright fulcrum member or bar 56 isfitted within an outwardly-opening recess 57 formed in a bracket 58depending `trom the outer side of said compressor arm and projectsupvi'ardly through an opening 59 in the outer end of the slide 54.Extending diagonally through an opening GO in the fulcrum bar andthrough an upright slot 6l in the bracket 58 is a bolt G2 and applied tothe inner end' of the latter is a coiled spring (3i-3 held in place by awasher G4 and nut 65. The purpose of this spring is to permit thesegment jaw or plate to adapt itself to irregular barrels, said spring`tending constantly to resist the outward movement of said plate.

Briefly stated, the operation of the machine is as follows:

Assume a. barrel to be in place on the base 1() and the compressor arms12, 12 to be in their normal open or expanded position. To close thearms around the barrel, the operator depresses the foot lever 88 toengage the clutch 32, 38 and rotate the toggle-actuating lever 18 fromthe position shown in Fig. 3 to that shown by full lines in 2, in whichposition they are locked, as previously described. The operator nowreleases the foot lever to disenga the clutch. After applying the endhoop or hoops to the barrel. he depresses the foot lever 45 to break thetoggle connection after which the spring 48 causes the compressor armsto be automatically returned to their open position.

Barrels of different sizes may be operated upon by this machine bvsimply substituting segmental jaws or plates 53 of dierent sizes.

Upon swinging the compressor arms apart the short arm of the bell crankoperating lever swings across the space between the axes of theoperating lever and the compressor arms and the long arm of the samemoves toward the rear of the axis of the operating lever, therebycompensating for this difference in the position of the arms of theoperating lever and causing both compressor arms to be opened and closeduniformly.

The mechanism for actuating the compressor arms imparts to them equalstrokes so that they move uniformly and simultaneously through the samedistance at substair tiallythe same speed, thereby bringing the barrelstaves together evenly and truly without danger of breakage.Furthermore, by this arrangement, an infinite amount of power isadvantageously appliedat the end of the closing stroke .of thecompressor arms, at a time when they greatest resistance is encounteredand a corresponding increase in power is required.
